STRAW-HAT-SEWING MAOHINE.

SPECIFICATION forming part of Letters Patent N0. 269,215, dated December 19,1882.

Applicaiion filed March 1, 1882. (Model) T0 all whom it mag; concern Be it known tbai: we, WILLIAM B. LASSCELL and CHARLESH.VVILLOOX, tbo former of Bayonne, Hudson county, New J erscy, and the latter of New York city, county and State of New York, have in'vented a new and useful lmprovemeut in Straw-Hat; Machines, which improvement is fully sei; forth in the following specificalzion.

'lhis invention has referenoe toatable adaptedto be brought into position to forn1 a coutinuation .of the sewing-machine work-plate, or to be rnoved out of tl1c way als the willof the operator. I is more particularly designed for use in rhe machines for sewing straw braid into a hat: in order to forxn a support in sewing to the tip or top of the crown of the hat, whence it1 is technically known ns a tiptable, but itcan be applied to other purposes. The objections to tbe ordinary xnethod of making tips (which this invention is designed to overcome) are, Lbat in rapid-running machines greal: care has to be usedin keeping the buhton or small circle of Lhe tip up to oho workguide, so that tl1e ncedle will stitoh through the 'nip and the entering braid. o1 plaib, and in doing this the operator unconsoiously crowds the tip up against the work-guide with more force than is necessary, and by so doing, as the tip grows in size, it: is made to assume a dishing or concave oondition, so tbat; after tbe Center than ab oho edge.

tip is turned down to sew tl1e crown, and after the crown is made, the tip will be found to be concave ordishing and mach lower ab the Tbis serious defecl: l1as to be ov-ercone by what is known as Lhe setting-up process, wbich includes stretching tbe tip over a block whilo web with a solution of glue-water, and he hat is lel't to dry on be block. After taking the hat: off tbe block, if the tip is found not stiff enough to stand up, it is further supported by putiing in a tip of p'aper on the under side of the hat-tip, with glue, and then set up again under heavy pressure in a. hydraulio press, all which operations are expensivo in time and labor. Now, if tho tip can be sewed flatfrom the button 01113 to the edge of the crown, the tip will remain flat and render the settingnp prooess unnecessary. ll1is is aocomplisbed by t-he flat tip-table, wbich scrves as a support to rest: tho tip upon,so that theoperatorcannot: make -the tip concave or (lishing, und by the cxer- -cise ot' the slightest care will make every tip nearly as Hai: as the tip-tablc itselt'. Tbe Lable is preferably rnaole tilting on a horizontal axis, and is upheld in position to forrn an e-xtension of the work-plate by lugs having inclined faces und hold in engagement; by a spring, so th-ao it can be removed b y simple prcssure of tho operators fingers on tbe table.

' lhe acconnmnying drawings, which form a parl: of this specitication, illustrate whal; is deemed tbe besb mcthod of carrying tl1e invention into efiect.

Fignre 1 is a, front elevation of part of a straw-hat-sowing machine provided with a tiptable Fig. 2, a view in plan and horizontal section, sbowing the construction of tbe tiptable a'nd the manner of its attachmenis; anal Figs. 3 and 4 are parti-al views, in perspective, cf be table detached.

Tbe tip-table consists ol a plate, A, fixed at the end of a supporting-arm, B, by means ot' a screw, a, and steady-pins a. The arm Bis provided at its inner end wil3l1 a hollow boss, b, wbich fits snugly within thc connterbored recess b in the nmcbine-l'rameb, and receives tl1e screw-stud D, wbich is tapped at its inner end into the nmchine-frame. 011 his stud D, between the end ol' tl1e boss b and tl1e bottom of the counterbored recess b, is a. washer, c, provided on its outer face wibb lugs c, and on the inner face groovcd, as sbown in Figs.3 und 4, or otherwise roughened. Wl1en tbe screw is in place the w-asher 0 is hold firmly between the slxoulder don the screw-slzud and tbe bot'oom of tbe rooess b, und the roughened inner surfaoe being pressed againsi: said botztom the Washer is eft'cctually prevented from tnrning. Screwed fast on tbe inner end of tho boss bis a ring, e, notcbed, as shown als e, to receive ehe lugs c. Tl1e notcbes e could be made in tl1e boss itself; bat as this would ordinarily be made of onst-iron in ono pieco with the arm B, it is preferrcd to use an additional steol rii1g.

A spring, E, is placed within tbe boss b, surrounding the shank ofstnd D, and bears ab one en(l against tl1e nnder side'of the head of the stud und ab the other against the interior shoulder f on the boss b. Tl1is spiingtends t0 force bossb and the arm B inward, and, When the lugs c are in tl1e notches e, itholds then1in engagewenn. Tl1e boss bis capableof asmal1 endwise movernenton tl1e stnd D and within theoounterbored recess b in tl1e maohine-frame. NVhen the arm B is tnrned tho inclined faces 0f t1i lngsc aot upon theinclined sides of thenotches e and i'orce the arm B und boss b outward against Ehe pressure of tl1e spring E. W'hen the arm B is turned a sufiioientdistanco to release tl1e lugs fron1 the notches, ii; will drop down by tlie action of grawity or will re1nain in any position in whioh it; may -be placed, und when in is tnrned back Ehe spring E foroes the boss l) witll tl1e notches c into engagemen with tl1e 1ugs c, wl1ioh uphold the arm B and plate A until snificient pressnre is applied to compress tl1e saidspring and retraot the boss. 'Ihe pin g holds Ehe washor c in place on the sorew when tlie tip-table is separate from the machino.

In attaching tl1o table to tl1o machine the lugs c 0n the washer c are made Eo take their position in the notohes e, and ehe boss Z) and screw-stud D are inserted in tl1e oounterbored reoess b. The plate A is adjnstecl against tho worlaplate Fof the sewing-rnachine flush with the top of said work-plate, and the stnd D is sorewed inL0 the fran1e, securing tl1e waslxor 0 in tl1e position it then ocoupies. Il1e roughness of the inner face of the washer prevents in i'r0n1 moving so that when turned up the plate A always comes so the proper position with respeot t0 the work-plate. In the maobine shown, as will be Seen from tl1e drawings, the work-plate is elevated by tl1e frame abovo Lhe table or stand on which i'm is placed.

G is the presser-foot of the sew-ingmaohine; H, tl1e workgnirle; 1 I, the guides f0r the entering braid. These parts may be of any ordinary or suibable construction. As shown, tl1ey am constructed substantially as lesoribed in Letters Patent N0.218413 grantv l to Charles H. Villoox August 12, 1879. In Fig. l the tip K and entering braid L are shown in dotted lines.

In operation tl1e tip can be, hold upon the plato A or tip-Lable, and, a slight resistanoe 'heing applied by the linaers of i:he Operator,

the entering braid L is fed along fast enougl1 to enable alle tip to be made' perfeotly flat. As soon as tl1e tip has been formed, a touoh ufthe band throws the tinplate out of action.

und the crown can then be tur ned down willi- 0ut interference froxn tl1e tip-table.

The machino is ordinarily snpportrd ab tl1e .edge of a bench or table, Q. so t.hat the \V0lkplate projecs beyond the benolx. \Vhen the tip-table is moved ontoi' action 113 drops down vertieally, tho arm B (shown in dotted lines, Fig. l) fitting into a groove, B, formed in the edge 0f oho benclx. 'lbe workplate is tl ms left: entirely iree. Tl1e tip-table is also shown in Fig. lin an intermediate position by dotted lines. In beginning a new tip tl1e plate A is moved back into its original posilion, in whieh it is hold by the engagement of tl1e lugs c in the notches c under izhe pressure of the spring E.

In is obvious thai: modificationsoan be made in the details of construction, and that parts of the invention rnay be used separately.

Having now fnlly described onr said invention, und the manner of carryingthe same into effeot, what wo claim is 1. The oombination, with a sewingmaohine, of a table movable int0 position to i'orm an extension of Ehe work-plate and capable of being thrown out; of aotion by pressure, as of the operators band applied to said table, substantially as described.

2. Tl1eoombirlzitionwith a sewi1ig-ma0hine, of a tilting tahle for1nerl of a plate, a supporting-arm attaohed to and depending i'roin the bottom oi' said plate, an l mcans for attaching tl1e arm to Llxe maohino-fraxne below the Workplate oi' tl1e 1nachiiie, substantially as clescribed.

Tl1e combination,with the sumwrting-arm, the hollow boss provided With' notebes, tl1e sorew, an l spring of tl1e washer roughened 0n one i'aoe and provided on the other with lugs adapted to engage said notohes, substantially as desoribed.

4. The ooxnbination, with a sewing-machine and the guides for sewi ng straw braid into a hat, of a mov'able tip-table adapted when in aetion to form an extension of t;l1e work-plate, and to be pnt into and out; of action, us re quired, so that the said machine is adapted to tl1e oontinuons sewing oi' Lhe orown of the hat, substantially as described.

5. Tl1e oombination, with a frame and an arm having a hollow boss titting within a ooun= terbored recoss in sai l frame, of the stud, spring, and lugs having inolined faces, substantially as desoribed.

6. 'lhe combination, with the work-plate and fra1ne of a sowing-machine, of atilting table oomprising a plate, supporting-arm with hollow boss having notches, serew-stud, washer provided with lugs, and spring, substanbially as described.

7. 'll1e oombination, with a sewing-maohine having a work-plate raised above the stand on.

- irarne, as explained, said table being adapted to be rnoved np to a lovel witl1 the work-plate or to be moved down out. 0[" action by pressure applied to the table, substantially as desoribed.
